STEAM-PLQW.

Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed April 24, 1907. Serial No. 370,014:-

To all whom it may concem:

Be it known that 1, lanes JoYoE, Jr., a citizen of the United States, residing at Sikeston, in the county of Scott and State of Missouri, have invented certain new and useful Improvements in Steam-Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make p a suitable carrying wheel B which is journaled in a and use same, reference being had to the accompanying drawings, and to the letters and figures of refegence marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in steam plows, and the object of the invention is to produce a simple and eflicient apparatus of this I nature whereby steam may be utilized for actuating -mechanism for raising plows when coming to obstructions, and for other purposes.

The invention consists in various details of construction and combinations and arrangements of parts suitable hanger (not shown), the shank portion of which is journaled in the arched yoke-B Fixed to said shank portion is a crank arm B pivoted to the bar B which in'turn is pivotally connected to the lever B fastenedto the stub shaft B which is journaled in a suitable bearing in the angle block B bolted or otherwise securedto the frame proper and also to the reinforcing or cross-beam A To the lower end of said stub shaft B is fixed a lever B to which the cables 0,

which are crossed, are fastened. Said cables are ;crossed in order to make the guide wheel'have the proper direction when turning.

I with stubble bottoms.

Fastened at intervals to the diagonally disposed portion of the frame is a series of hitching clips or braces D, which are made preferably of metal, and

each of said hitching clips has a forked end D, the

arms of which carry apin D upon which the adjustable perforated plates D are mounted, which plates are bolted or otherwise secured to the forward ends of the plow beams E. E designates plows, preferably Fastened to the side of each of said beams E is a resilient hook F, being held normally in a closed relation against the beam to which it isfastened and is designed to hold a ring F to which the rods F having eyes at the ends are connected. By these rods and rings, it will be noted that the various, plow beams are connected together, and by the construction shown, means is provided whereby in the event of any of the plows catching upon an obstruction and throwing the same out of the ground, that particular plow will be detached from the other series without injuring the same.

A lifting beam G is connected by means of chains G" with each plow beam, said chain having direct connection with one of the rings F as shown, and H, H designate lifting cranes-which are fastened at their forward ends to the main frame of the apparatus and carry the grooved sheaves Kand L, the former of which are journaled at the rear forked ends of said lifting cranes and are vertically disposed, while said sheaves L are horizontally journaled and near the inner ends of said cranes.

N designates a steam cylinder having a piston rod N adapted to be driven by a piston mounted within said cylinder, and O designates a chain which is fastened at one end to said piston rod and passing about the two sheaves K and L, is fastened to said lifting beam G. I

Q designates a second steam cylinder having a piston stem Q actuated by a piston within the cylinder Q, and R designates a chain which is fastened to the piston stem Q, passes about two of the sheaves L and K, as shown, and is fastened to the lifting beam G. A steam pipe S communicates with said cylinders, and

branching from said pipe is a supply pipe T which is adapted to have direct communication with a steam boiler (not shown) of a traction engine.

v The operation of my invention will be readily understood and is as follows. The plow frame is adapted to be' connected to any form of traction engine, and the apparatus shown is adapted to turn six furrows at once, although it will be understood that any number of plows may be utilized as may be desired, and in the event of it being desired to raise the plows for any purpose, it may be done by causing steam to act upon the pistonswithin said cylinders which will cause the'lifting bar and the plows attached thereto to be raised from the ground. In the event of any one of the plows striking an obstruction, the hinged hooks fastened to the plow beams will open and allow the particular plow which meets the obstruction to be detached from the others without injury to the same.

What I claim is:-

through said lateral projection, a bearing block mounted within each casing and carrying a caster wheel, and detachable connections between said plow beam, as set forth. I

2. A steam plow comprising a frame, a series of pivotally mounted plow beams thereon, steam actuated mechanism for raising and lowering the beams, each of said beams having a lateral projection, a boxing having open faces through which said lateral projection extends, a screw swiveled in the top of eachcasing and passing through said lateral projection, a bearing block mounted within each casing and carrying a caster wheel, :1 resilient finger mounted upon the face of each beam, the free portlon of each finger belng slightly curved, a ring normally held by the curved finger and rods connecting the rings held by said finger, as set forth.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
